This paper describes optimum values of a circuit and an additional vibration system for energy harvesting using electromagnetic induction or the piezoelectric effect with considering the vibration characteristics of vibration sources. When the mechanical impedance of the additional vibration system is significantly smaller than that of the vibration source, the vibration characteristic of the vibration source is negligible. However, in certain cases, the mechanical impedance of the additional vibration system is not significantly small. Therefore, the optimum values for such cases were formulated in this study. The effectiveness of the optimum values was verified through simulations.
